Description

Technical Field

[0001] This utility model relates to the field of calcium oxide preparation technology, specifically to a raw material screening device for preparing high-quality calcium oxide. Background Technology

[0002] Calcium oxide is an inorganic compound, commonly known as quicklime. Its physical properties are that it is a white powder on the surface, grayish-white when impure, and pale yellow or gray when containing impurities. It is hygroscopic. In the production process of calcium oxide, screening is required, which necessitates the use of screening devices.

[0003] The application for a raw material screening device for calcium hydroxide preparation, with application number 202123387668.0, achieves a three-stage screening function through an inclined trough, a first filter screen, and a second filter screen, thereby increasing the screening effect. Furthermore, through the coordinated use of inclined blocks, a moving trough, a motor, a threaded shaft, a moving rod, a first connecting rod, a second connecting rod, a second connecting rod, a first inclined hole, a second inclined hole, a third inclined hole, a first scraper, a second scraper, and a third scraper, the first filter screen, the second filter screen, and the inclined trough can be cleaned simultaneously, increasing the cleaning efficiency so as not to affect the next screening operation.

[0004] While the above-mentioned applications meet the user's needs to a certain extent, certain defects still exist during use. Specific problems are as follows: after the raw materials are poured into the screen, they are prone to clogging of the screen holes due to accumulation. The raw materials are also unevenly distributed on the screen, with some areas having too much raw material that cannot be fully screened, resulting in fine materials mixed with coarse materials or coarse materials leaving fine materials behind, leading to low screening accuracy. When collecting calcium oxide, the collection components are mostly fixed single collection boxes. When the collection box is full, the screening equipment must be stopped before it can be disassembled and cleaned, causing the screening process to be interrupted. Especially in batch screening scenarios, frequent shutdowns and box replacements significantly reduce overall production efficiency. Furthermore, the collection box lacks a vibration-assisted structure, and the collected raw materials are prone to accumulating and clumping inside the box, occupying collection space. Based on this, this utility model designs a raw material screening device for high-quality calcium oxide preparation to solve the above problems. Utility Model Content

[0005] This invention provides a raw material screening device for high-quality calcium oxide preparation, which can effectively solve the problems mentioned in the background art, such as the easy accumulation of raw materials after being poured into the screen, leading to local screen hole blockage, uneven distribution of raw materials on the screen, and excessively thick raw materials in some areas that cannot be fully screened, resulting in fine materials mixed with coarse materials or coarse materials leaving fine materials, resulting in low screening accuracy. When collecting calcium oxide, the collection components are mostly fixed single collection boxes. When the collection box is full, the screening equipment must be stopped to disassemble and clean it, which leads to the interruption of the screening process. Especially in batch screening scenarios, frequent shutdowns and box replacements significantly reduce the overall production efficiency. In addition, the collection box lacks a vibration-assisted structure, and the collected raw materials are prone to accumulating and clumping inside the box, occupying collection space.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material screening device for preparing high-quality calcium oxide, comprising a base, on the top of which shock-absorbing springs are uniformly welded, and the tops of several shock-absorbing springs are connected by a screening box, a screen is installed inside the screening box by screws, and a vibration motor is installed at the bottom of the screening box by screws; The screening box is equipped with a push rod and an extension rod for pushing calcium oxide. The push rod is driven by a drive motor and a reciprocating screw. Both ends of the base are provided with collection boxes for collecting calcium oxide. The collection boxes can vibrate with the vibration of the screening box.

[0007] A raw material screening device for preparing high-quality calcium oxide, preferably, has a drive motor mounted on one end of the top of the screening box by screws, a reciprocating lead screw fixedly connected to the output shaft of the drive motor, a moving rod connected to the outside of the reciprocating lead screw by threads, a pushing rod mounted on the bottom of the moving rod by screws, an adjusting screw connected to the inside of the pushing rod by threads, and an extension rod connected to the bottom of the adjusting screw by threads.

[0008] A raw material screening device for the preparation of high-quality calcium oxide, preferably wherein the end face of the push rod is in contact with one end of the inner wall of the screening box, and the extension rod is slidably connected inside the push rod.

[0009] A raw material screening device for the preparation of high-quality calcium oxide, preferably, has two collection boxes at both ends of the base, which are connected by a connecting rod. Multiple connecting springs are uniformly welded to one bottom end of each collection box, and one end of each pair of adjacent connecting springs is connected by a sliding rod. A drive rod is installed on the top of the collection box by screws.

[0010] A raw material screening device for the preparation of high-quality calcium oxide, preferably wherein the driving rod, extension rod and connecting rod are all T-shaped.

[0011] A raw material screening device for the preparation of high-quality calcium oxide, preferably wherein the driving rod is slidably connected inside the screening box and the extension rod is slidably connected inside the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The structure of this utility model is scientific and reasonable, and it is safe and convenient to use: It can evenly spread the piled raw materials on the screen, avoiding local blockage and excessive material thickness, ensuring that the screen fully contacts the raw materials, and the pushing process can change the movement trajectory of the raw materials, prolonging the residence time of the raw materials on the screen, allowing fine materials to fully pass through the screen holes and coarse materials to be accurately intercepted, greatly improving the screening accuracy. The length of the extension rod can be adjusted according to the screen width and the material accumulation, adapting to the pushing needs of different screen specifications, further ensuring the uniform distribution of raw materials on the screen. Two sets of sliding collection boxes are installed at both ends of the base. They are flexibly moved by sliding connections between the drive rod and the screening box, and between the slide rod and the base. During screening, one set of collection boxes receives the undersized fine material. When the set of collection boxes is full, it can be directly slid to switch to another empty set of collection boxes to continue collecting without stopping the screening equipment, thus achieving continuous screening and collection. The bottom of the collection box is connected to the slide rod by a connecting spring. The vibration of the screening box can be transmitted to the collection box through the drive rod, so that the collection box vibrates slightly synchronously with the screening box, avoiding the accumulation and clumping of raw materials in the box, maximizing the use of collection space, reducing subsequent raw material processing steps, and lowering operating costs.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figure 1-4 As shown, this utility model provides a technical solution: a raw material screening device for preparing high-quality calcium oxide, including a base 1, with shock-absorbing springs 2 uniformly welded to the top of the base 1, and several shock-absorbing springs 2 connected to each other by a screening box 3. A screen 4 is installed inside the screening box 3 by screws, and a vibration motor 5 is installed at the bottom of the screening box 3 by screws. A drive motor 6 is mounted on one end of the top of the screening box 3 by screws. A reciprocating screw 7 is fixedly connected to the output shaft of the drive motor 6. A moving rod 8 is threadedly connected to the outside of the reciprocating screw 7. A push rod 9 is mounted on the bottom of the moving rod 8 by screws. An adjusting screw 10 is threadedly connected inside the push rod 9. An extension rod 11 is threadedly connected to the bottom of the adjusting screw 10.

[0017] The end face of the push rod 9 is in contact with one end of the inner wall of the screening box 3. The extension rod 11 is slidably connected inside the push rod 9 to ensure the stability of the movement of the push rod 9 and the extension rod 11 and to avoid the problem of rotation when the push rod 9 and the extension rod 11 move.

[0018] Two collection boxes 14 are provided at both ends of the base 1. The two collection boxes 14 are connected by a connecting rod 15. Multiple connecting springs 13 are evenly welded to one end of the bottom of the collection box 14. One end of multiple adjacent connecting springs 13 is connected by a sliding rod 12. A drive rod 16 is installed on the top of the collection box 14 by screws.

[0019] The driving rod 16, extension rod 11 and connecting rod 15 are all T-shaped. The driving rod 16 is slidably connected inside the screening box 3, and the extension rod 11 is slidably connected inside the base 1, which facilitates the fixing and limiting of the collection box 14, thereby achieving the fixing of the collection box 14.

[0020] Personnel move the sliding rod 12 into the base 1 by moving the collection box 14, and move the driving rod 16 into the screening box 3. Personnel adjust the position of the extension rod 11 by rotating the adjusting screw 10. After adjusting the extension rod 11 to the appropriate position, personnel turn on the vibration motor 5 to make the screening box 3 and the screen 4 vibrate. Calcium oxide is poured into the top end of the screening box 3. At this time, the calcium oxide is screened through the screen 4. During this process, the drive motor 6 is turned on to drive the reciprocating screw 7 to rotate. Through the threaded connection between the reciprocating screw 7 and the moving rod 8, the moving rod 8 can be moved, which in turn moves the calcium oxide on the top of the screen 4, so that the calcium oxide can be evenly spread on the top of the screen 4, which can better screen the calcium oxide, improve the screening effect of calcium oxide, and avoid the problem of poor calcium oxide screening effect caused by calcium oxide accumulation. In addition, the adjustment of the extension rod 11 makes it easy to screen calcium oxide of different sizes. During the screening process, the screened calcium oxide falls into the collection box 14. At this time, the vibration of the screening box 3 will cause the collection box 14 to vibrate, which will also cause the calcium oxide inside the collection box 14 to vibrate. This allows the calcium oxide to be evenly distributed inside the collection box 14, so that more calcium oxide can be collected inside the collection box 14. By moving the two collection boxes 14, one collection box 14 is moved to one end of the screen 4, and the other collection box 14 is moved out of the base 1. At this time, by moving the other collection box 14, the two collection boxes 14 can be separated, and the calcium oxide inside the collection box 14 can be processed without stopping the screening of calcium oxide, which can further improve the screening efficiency of calcium oxide.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
